Selection of Die Materials and Surface Treatments for Increasing Die Life in Hot and Warm Forging
In warm and hot forging, the dies are subjected to high contact pressures and temperatures. The selection of the die material, hardness and coating is critical for increasing die life. Recent studies indicate that ceramic dies and various surface treatment techniques represent, in certain applications, cost effective techniques for improving die life. This paper reviews the state of technology ...
متن کاملEnhancement of hot forging die life using different methods
Forging dies at high temperatures are under contact pressure, variable mechanical loads and thermal shock, furthermore they should withstand wear and friction in a high level. So, in order to increase die life, the selection of die material, coating and hardness is essential. In this review, various methods used for die life enhancement such as carbide coating, using the super alloy stellite 6 ...
متن کاملEffect of Shot Peening Treatment on Forging Die Life
The aim of this paper was to study the effects of die life through shot peening treatments on AISI H13 steel, and tests were performed to study the influential parameters of the shot peening process. To evaluate the effects of microstructure and the die life of AISI H13 steel after steel shot peening processes, we conducted and evaluated roughness tests, micro hardness and wear tests, and SEM m...
متن کاملEstimation of Spray Lubrication and Die Temperature for Die Wear Life Prediction in Hot Forging
We have been developing a process design CAE system to predict die wear life in the process design stage for the hot forging of steel. Our goal is to reduce production costs by shortening the development period, while maximizing the life of the die. In our system, we use an expression that defines the relationship between die wear, die strength, and friction factors, such as die pressure, slidi...
