Soft Sensors for Property-Controlled Multi-Stage Press Hardening of 22MnB5
AbstractIn multi-stage press hardening, the product properties are determined by the thermo-mechanical history during the sequence of heat treatment and forming steps. To measure these properties and finally to control them by feedback, two soft sensors are developed in this work. The press hardening of 22MnB5 sheet material in a progressive die, where

Transformation Characteristics and Properties of B Steel 22MnB5
Abstract Continuous cooling transformation characteristics of steel 22MnB5 were studied in detail using dilatometer method. The influence of hot forming procedure parameters, such as heating rate, austenizing temperature, and holding time on microstructure transition was analyzed. Microhardness was tested afterwards.

Optimizing Advanced High‐Strength Steel Joints via Regional Rapid Cooling in Resistance Spot Welding
The study introduces a new methodology to control microstructural differentiations and internal stresses in martensitic steels’ heat‐affected zones during resistance spot welding (RSW). Utilizing a unique prototype setup based on the regional rapid cooling (RRC) process, the method optimizes material performance by narrowing the heat‐affected zone ...
