Abstract:

As a rule, austempering and martempering processes are performed in melted salts and alkalis that is not environment friendly technology which has
several restrictions due to slow cooling. The paper discusses unexpected and cardinally new technologies. Austempering and martempering processes are performed intensively in environment friendly water solutions or just in plain water under pressure. Due to intensive cooling, all restrictions are released and several opportunities are added such as combining austempering with the HTMT and LTMT processes. The new technologies are based on self – regulated thermal process (SRTP) meaning maintenance the surface temperature of steel parts at the level of boiling point of a cold liquid. Based on SRTP, the recipes calculations are considerably simplified, more accurate and understandable. The paper can be useful for engineers and scientists dealing with the improvement the quality of materials.

Keywords:

Nucleate boiling, Self – regulated thermal process, Intensive austempering and martempering, Simplified calculations, Accuracy, Benefits.
