Otomotiv gibi endüstriyel alanlarda kullanılan östenitik paslanmaz çelik yüksek fiziksel ve mekaniksel özelliklere sahiptir. Bu çalışmada benzer ya da benzere yakın şekilli ürün ve karmaşık şekilli malzeme üretilmesine olanak sağlanmasından dolayı araştırmacılar tarafından cazip görülen toz metalurjisi yöntemiyle hazırlanan 316L östenitik paslanmaz çeliğin termofiziksel özellikleri araştırılmıştır. Östenitik paslanmaz çelikler 400 ve 600 MPa basınçlarında preslenmiş ve preslenen östenitik paslanmaz çelik numuneler 1200 °C sıcaklığında 1 sa boyunca inert gaz atmosferinde sinterlenmiştir. Bu sinterlenmiş östenitik paslanmaz çeliklerin termofiziksel özellikleri oda sıcaklığından 600 °C’ye kadar olan sıcaklık aralığında ısı akısı tipli Diferansiyel Taramalı Kalorimetreyle (DSC) ile ölçülmüştür. Bu özellikler SEM görüntüleri, EDS spektrumları ve OM (optik mikroskop) görüntüleri ile desteklenmiştir.

Pressure Influence on the Thermophysical Properties of 316L Austenitic Stainless Steels Manufactured By Powder Metallurgy Method

Öz

Austenitic stainless steel that is used in the industrial areas such as automotive has high physical and mechanical properties. In this study; thermophysical properties of 316L austenitic stainless steel prepared by powder metallurgy method that is attracted for researchers due to obtain net or near shaped product and complex shaped materials, have been investigated. Austenitic stainless steels pressed on the 400 and 600MPa pressures and pressed austenitic stainless steel samples sintered at 1200 °C temperature for an hour under inert gas atmosphere. The thermophysical features o these sintered austenitic stainless steel were performed at temperature ranging from RT to 600 °C via heat flux type Differential Scanning Calorimeter (DSC). These properties supported by SEM images, EDS spectrums and OM (Optic microscope) images.
