Effects of Overheating on Fatigue Strength and Fracture Toughness of 40CrMnSiMoVA Steel During Forging
Abstract
This paper studies the effects of overheating on fatigue strength and fracture toughness of 40CrMnSiMoVA steel during forging. The experiments are carried out on the BX-type large-size......
Defects and Prevention of Liquid Die Forgings: Abnormal Segregation
Abstract
Liquefied model forging is a process that enhances the mechanical properties of metals and alloys. However, during this process, defects may occur due to problems such as improper operation of the equipment, inappropriate design, severe high temperature gradients, and excessive frictio......
Forging Technology: Design of Hot Forging Drawings in Die Forging
Design of Hot Forging Part in Die Forging
Hot forging is the process by which metallic parts are formed into different shapes under high temperature. It can be used to produce parts with high toughness, strength and wear resistance. Hot forging is a process that takes place in a die, formed from ......
