Retained Austenite Control for the Soft Machining of High-Hardness Tool Steels
(MDPI, 2018-07-23)
Most high-hardness tool steels comprising forming dies require expensive finish machining operations to compensate for the dimensional distortion and surface oxidation caused by the die heat treatment. Precipitation-hardening ...
Wear And Friction Evaluation Of Different Tool Steels For Hot Stamping
(Hindawi, 2018-03-26)
The aim of this work is to investigate the durability of tool steels for hot stamping by comparing the wear resistance of three hot work tool steels. Friction and wear behaviours of different tool steels sliding against a ...
Design, Construction and Testing of a Hydraulic Power Take-Off for Wave Energy Converters
(MDPI, 2012-06)
This paper presents the construction, mathematical modeling and testing of a scaled universal hydraulic Power Take-Off (PTO) device for Wave Energy Converters (WECs). A specific prototype and test bench were designed and ...
Framework for the Shape Optimization of Aerodynamic Profiles Using Genetic Algorithms
(Hindawi Publishing Corporation, 2013)
This study developed a framework for the shape optimization of aerodynamics profiles using computational fluid dynamics (CFD) and genetic algorithms. Agenetic algorithm code and a commercial CFD code were integrated to ...
Effect of the Martensitic Transformation on the Stamping Force and Cycle Time of Hot Stamping Parts
(MDPI, 2018-06)
Stamping dies perform two functions in the hot stamping process of body-in-white components. Firstly, they form the steel sheet into the desired shape and, secondly, they quench the steel at a cooling rate that leads to ...
