hot shortness

The degree of hot shortness is in direct proportion to the amount of sulfur present.

It is well known that nickel is a beneficial alloying element in copper bearing steels as it prevents hot shortness.

He is now working on a Ph.D. by research titled "Surface Hot Shortness in Low Carbon Steels" under the supervision of Prof.

The thermodynamic considerations were also applied to a quantitative discussion on hot shortness and some measures for preventing hot shortness of copper bearing steels were suggested.

The report encompassed the effects of the residuals on hot shortness and hot ductility, scale formation and adherence, embrittlement and mechanical properties, weldability, corrosion, and galvanizing properties.

The advantages of this over hot extrusion are the lack of oxidation, higher strength due to cold working, closer tolerances, better surface finish, and fast extrusion speeds if the material is subject to hot shortness.

In the second phase, MTL is evaluating and characterising the effect of residuals in two selected grades of steel (low and medium carbon) on hot ductility and hot shortness, scale formation and adherence, and mechanical properties.
