Hot Torsion Testing Determines Metals Workability

New torsion testing e quipment designs offer state-of-the-art instrumentation and provide enhanced capabilities including greater speed, measurement accuracy, and flexibility of experiment design.

Metals workability generally is defined as the ability to form a metal into a particular shape by means of applying a load to the metal via some type of equipment or tooling without causing the metal to fracture or to have an undesirable microstructure. Workability of a material is determined from several factors including strain, strain rate, temperature, failure behavior, and others. Mechanical tests, such as tension and compression tests alone are not capable of providing all of this information. However, the torsion test can provide flow stress data and failure and microstructural response to deformation processing. Gleeble systems offer dynamic thermal-mechanical test capabilities, such as hot torsion testing, simulating thermal and mechanical parameters under very precisely controlled conditions.
