Strain Rate Dependence of the Tensile Flow Stress of Pure Tantalum

Strain Rate Dependence of the Tensile Flow Stress of Pure Tantalum

Strain rate and temperature dependence of flow properties of tantalum or tantalum alloy is very important from an engineering standpoints and in viewpoints of technical application of these metals or alloys at cryogenic temperature service.

In the present study, the flow or yielding behaviors of electron beam melted pure tantalum were studied experimentally mainly in viewpoints of strain rate or temperature dependence of the flow and yield (0.2% proof) stress of pure tantalum.

Activation energy or activation volume and frequency factor etc, which are directly linked with dislocation behaviors of the pure tantalum, were also evaluated from macroscale measurements in tensile testapplying incremental strain rate or temperature change test of the temperature and strain rate dependent tensile properties of the electron beam melted pure tantalum encountered in low temperature testing.

Mechanical Ball Seat

Mechanical ball seat is a device that temporarily plugs the running string to provide the pressure-tight chamber necessary to hydraulically activate the liner hanger or release the running tools.

The temporary plug is created by dropping a setting ball that lands in a steel ball seat that is sheared out and retains the ball when the plug is no longer needed. The mechanical ball seat is located inside a sub in the running string, below the hanger and above the liner-wiper plug of the liner-hanger system. Before dropping the setting ball, the ball seat allows passage of a smaller trip ball to activate equipment below the liner hanger and running equipment, such as auto-fill float equipment, or a Defyer™ drill assembly. The primary setting ball is then used by the mechanical ball seat to isolate pressure above the ball seat. Upon completion of the hydraulic events, the ball seat shears with application of predetermined amounts of pressure and locks into the bypass position within the sub. With the ball seat in this location, pressure surge on the formation is eliminated or reduced when the ball seat shears.

If cementing plugs are run, they are located just below the mechanical ball seat and may sustain damage by the pressure surge. In this case, the energy-absorption tool (EAT) is placed between the plugs and the mechanical ball seat to diffuse the pressure surge before it reaches the plugs, saving them from damage. After the mechanical ball seat is deactivated, the ball is trapped in the body, and the mechanical ball seat is opened full-bore for passage of drillpipe darts. In the event the ball seat cannot shear, a backup rupture disk opens to establish circulation.

The mechanical ball seat can operate in both horizontal and vertical wells and is recommended for pressure-sensitive formations and casing designs with close-tolerance annuli. The mechanical ball seat is also valuable in drilldown applications where higher hydraulic setting pressures are required to prevent premature activation of hydraulic set tools by unexpected pressure spikes.

How do you use woodworking inserts?

Shop fixtures and jigs often require the installation of various clamping or adjustment knobs. That’s when you’ll reach for threaded woodworking inserts.

Use thread-in woodworking inserts in softer woods and plywood where their coarse outside threads cut easily into the surrounding wood. Simply drill a hole sized for the body of the insert, and screw it into place. In very hard woods, such as white oak and maple, or when the insert is close to the edge of a part and screwing it in may split the wood, drill a hole slightly larger than the outside thread diameter, and epoxy the insert in place. To protect the internal threads from epoxy, cover the end of the insert, as shown below.

Press-in woodworking inserts, with their barbed exteriors, work well in hard woods, soft woods, and plywood. Drill a hole sized for the body of the insert, and press it into place with a clamp or tap it in with a hammer and a block of wood. For applications in which the clamping action tends to pull the insert out of the wood, such as the knobs that tighten down on a drill-press fence extension, drill a hole that engages just the tips of the insert barbs and epoxy it in place.

Benefits of Choosing Carbide Saw Tips for Your Metal Service Center

Any metal-cutting expert knows that having the right blade for the job is critical. Although it may seem like a small operational detail, blade performance impacts several key business areas, including productivity, maintenance, quality, and tooling costs.

Like any purchasing decision, blade selection needs to be strategic, taking into consideration a host of variables—business goals, material type, equipment, and operator skill level, to name just a few. Blade performance is also based on several variables—the cutting application, blade specification, number of teeth per inch, tooth set, etc. Put simply, not every blade is created equal, and choosing the wrong blade can result in poor quality cutting and higher operational costs.

The problem is that many of today’s service centers don’t even realize they are using the “wrong” blade. In many cases, companies settle for “good” instead of “great.” Managers and operators become content with the blade technology they’ve been using for years and end up missing out on the benefits a new blade technology could bring to their operation.

This is a common occurrence in band sawing. For example, many service centers have used bi-metal band saw blades over the years and have had decent results. And in many cases, bi-metal blades are a good choice. However, there are applications in which carbide saw tips technology would be the better choice.

Many companies are finding that making the switch to carbide saw tips technology can provide savings and productivity gains they would never have achieved with bi-metal blades.

To gain more performance out of its band saws, we decided to upgrade to carbide saw tips. Carbide saw tips use strong, durable materials to provide high performance, faster cutting, and prolonged blade life. The blade tooth has carbide saw tips welded to a high-strength alloy backing, allowing the metal service center to take on hard, nickel-based alloys, as well as stainless steel, tool steel, and titanium.

What are carbide rods used for?

What are carbide rods?

Carbide rods are made of WC as the main raw material, plus other precious metals and paste phases, which are pressed and sintered by powder metallurgy. Carbide rods have the characteristics of high hardness and high strength, and they penetrate into all areas of our lives.

Uses of carbide rods:

  1. Carbide rods are used in the field of mechanical production and processing

Micro-drills in the PCB industry, electrode rods in the optoelectronic communication industry, cemented carbide drill bits, milling cutters, reamers, ejector rods, push rods, wear-resistant precision parts, integral CNC milling cutters and machining tools with holes in the machining industry.

The difference between the alloy grades of the carbide rods processed with 45 degrees and 55 degrees: When processing HRC45 material, consider using BT45 grade. For processing 55 degree materials, consider using BT55 grade.

  1. Carbide rods are used as punches

Commonly used as a core rod. When it comes to punching needles, I have to explain the stamping die. Punching needles are an indispensable accessory when the stamping die is working. It is installed on the stamping die for continuous blanking, stamping, and punching operations to separate or plastically deform the processed materials, so as to obtain the desired finished product or semi-finished product.

  1. Carbide rods in furniture industry

Commonly used in computer engraving sharp knives.

  1. Carbide rods are used in the medical equipment industry

Commonly ones are integral cemented carbide steel burs for dentistry.
