cold work

Due to the growing demand for cold-work tool steel in various industrial applications, it is crucial to improve the fabrication technique because complex shapes involve an extensive and costly workshop effort.

There have been many recent wear-resistance advances, culminating in D7, hardened to Rc 67, the best abrasion-resistant tool steel for cold-work applications.

Both columns contain steels for cold-work tools and dies.

"The initial change in structure and properties that occur upon annealing a cold-worked metal is considered the beginning of recovery.

Intended for graduate students, researchers, and working engineers, articles discuss such topics as local and nonlocal modeling of ductile damage, predicting thermal properties of metallic hollow sphere structures, modeling semi-solid metallic alloys, functionally graded piezoelectric material systems and strength predictions for cold-worked polycrystalline metals.

For dry cutting of cold-worked steel 1.2379 and hot-worked steel 1.2344 with solid-carbide ball-nose endmills, the wear to the cutting edges of tools with AlTiN-Saturn coatings is far less than that of all TiAlN competitor coatings (Fig.

By this time, the pipe has lost some of its elasticity and cracks are introduced in this cold-worked region of the pipe.

The valves are available in 316 cold-worked stainless steel, with glass-filled Teflon packing, glass-filled PEEK seats, and Viton seals.

He is described as being "intuitively mesmerized by the fluid immediacy of molten glass and the brittle, unforgiving character of cold-worked glass." Relentlessly, Cohn has spent days, and sometimes weeks, sculpting, blowing, and redoing an element on a piece.

Clearly, in many instances of fatal explosions, the operational stress of the boiler could well have been within safe limits, but the residual stress in the steel around the rivet holes or other highly cold-worked areas would have been more than enough to initiate cracks through the thickness of the plates.

According to Tim Burstein, the metallurgy professor who headed up the work, electrochemically induced annealing maintains the desirable cold-worked hardness of steel while eliminating the brittle martensitic phase.
