Hot Working Simulation by Hot Torsion Testing
2005Abstract This article summarizes the types of hot working simulation tests such as hot tension, compression, and torsion testing used in the assessment of workability. It illustrates the use of hot torsion testing for the optimization of hot working processes.

Electrical hot work safety program
IEEE Transactions on Industry Applications, 1988An internal review of the safety practices for a large Canadian chemical plant indicated that the established procedures for electrical hot work needed to be expanded and formalized. The practices were expanded into a comprehensive electrical hot work program that included the philosophy, control, qualification, and safe work methods.

Safe Working in Hot Weather Conditions
SPE Symposium: Asia Pacific Health, Safety, Security, Environment and Social Responsibility, 2019Abstract The commitment of Oil Spill Response Limited (OSRL) to "provide resources to respond to oil spills efficiently and effectively on a global basis" to the industry is principally founded on the health, safety and well being of personnel; fundamental to the business is the effective management of health and safety risks.

Sedentary Work by Females in Hot Environments
Proceedings of the Human Factors Society Annual Meeting, 1975Performance by females on sedentary work tasks did not show meaningful decrement as a function of work place temperatures. In general, females showed less effect on performance in hot environments than did male subjects engaged in the same work activities.

Thermal fatigue in hot‐working tools
Scandinavian Journal of Metallurgy, 2005Hot‐working, in general, is one of the fundaments of the industrialised society and the hot‐work tool, which gives the part its basic shape, is one of the most essential elements. Most hot‐working tools are subjected to extreme temperature variations, which give rise to stresses and strains and may eventually lead to thermal fatigue.Two hot forming ...

A Simple Constitutive Model for Prediction of Single-Peak Flow Curves Under Hot Working Conditions
, 2016The hot flow stress of a typical stainless steel was modeled by the Hollomon equation, a modified form of the Hollomon equation, and another modified form based on the Fields–Backofen equation. The coupled effect of the deformation temperature and strain

Damage in hot rolling work rolls
Wear, 1999Samples from a couple of work rolls employed in a hot rolling steel strip mill were examined by scanning electron microscopy in order to study their surface, as well as the wear mechanisms responsible for their damage. It was found that a series of cracks develop within the rolls at the beginning of their operational cycle, these cracks follow the ...

Hot Working of Alnico 5 Alloys
Journal of Applied Physics, 1960Alnico permanent magnet alloys have been successfully shaped into rod, wire and strip by hot working at elevated temperature. It has been found that by careful processing, certain Alnico alloys can be fabricated by extrusion, swaging, and rolling. The wrought Alnico after heat treatment was found to have comparable permanent magnet properties and ...

Hot Working of the ZEK200 Magnesium Alloy
Materials Science Forum, 2008The high temperature workability of the ZEK200 Mg-alloy produced by Direct Chill casting (DC) was investigated by torsion testing between 200 and 450°C. The alloy exhibited a higher strength and a slightly lower equivalent strain to fracture than AZ31 and ZM21 produced by DC.

Effect of hot work on the properties of Waspaloy
Metallurgical Transactions, 1970The effects of process history on the properties and microstructure of wrought Waspaloy have been investigated. Forge practice is shown to be critical if the forging temperature exceeds theγ′ solution temperature. A light reduction at high temperatures decreases fracture ductility as evaluated by impact, tensile and rupture tests.
