Hey there Paewand Ochiha! Based on my education in secondary steel making from NISST, I can give you some general insights into tempering processes and their effects on steel.

Aus tempering and Mur tempering are heat treatment processes that influence the microstructure and mechanical properties of steel. Aus tempering involves heating the steel to a specific temperature range, holding it at that temperature, and then cooling it. Mur tempering, on the other hand, is a form of martempering where the steel is quenched to a temperature just above the martensitic transformation range and held until the temperature is uniform throughout the material before cooling.

The mechanical properties, such as hardness, toughness, and strength, can be significantly influenced by the tempering process. The choice between Aus tempering and Mur tempering may depend on the desired balance of these properties for a specific application.

For more detailed and accurate information, it's advisable to check recent research papers or publications in metallurgy and materials science journals. The field is continually evolving, and up-to-date sources will provide the most accurate insights into the impact of these tempering processes on (1050) medium carbon steel.
