Öndeformasyon ve Fırınlama Sıcaklığının Fırınlama Sırasında Şertleşen Çeliklerin Sertleşme Özelliğine Etkisi

Abstract

Yakıt tüketimini düşürmek ve bu şekilde egzoz gazlarının çevreye verdiği zararı en aza indirmek amacıyla otomotiv gövde ağırlığının azaltılması son yıllarda otomotiv sanayindeki en önemli beklentilerden birisidir. Arzu edilen özellikler fırınlama sırasında sertleşen çeliklerle elde edilmiştir. Ancak fırınlama sırasında sertleşme özelliği ön deformasyon miktarı ve fırınlama sıcaklığına bağlı olarak değişmektedir.

Effect of Predeformation and Baking Temperature on Hardening Property of Bake Hardening Steels

Abstract

The reduction of body weight of automotive in order to reduce the fuel consumption, thus gas emissions is one of the most important expectations in automotive industry. These properties have been achieved by bake hardening steels. However, bake hardenability property can be influenced by the amount of predeformation and baking temperatures.

Keywords
