Hot-rolled steel products with high strength and good formability are in demand for automobile body parts, particularly steels which can reduce weight without sacrificing vehicle safety. Recent studies have suggested that interphase precipitation (IP) hardening is a promising approach for obtaining excellent high strength and superior formability from low-alloy steels. However, the effects of hot rolling conditions and alloying elements on IP hardening have not been clearly determined. In this study, we sought to clarify the above effects by analyzing the recrystallization behavior during hot rolling. As a result of sample testing and analysis, it was determined that the recrystallization which occurs during hot rolling plays a critical role in enhancing the IP hardening of low-alloy steels.

This study aims to clarify the current status of the preservation and utilization of Rural People Interaction Heritage Systems (RPIHS) for the restoration of depopulated rural areas based on a case...

We reported outline of house recovery policy and marked them in the stricken area of Noto Peninsula earthquake in the March of 2007. And we clarified the actual situation of disaster public housing in case of Touge, village Wajima city where is near to the hypocenter and has sustained great damage. We marked them in the point aimed at building process, and defaine reasons of moving, community relations. and attributes of tenants, of Shofudai Disaster Public Housing.
