Abstract

Gözenekli
NiTi şekil hatırlamalı alaşım (ŞHA) toz metalurji yöntemlerinden
kendi-ilerleyen yüksek-sıcaklık sentezi (SHS= self-propagating high-temperature
synthesis) ile üretildi ve ön ısıtma sıcaklığının gözenek oluşumu üzerindeki
etkileri incelendi. Ön ısıtma sıcaklığının artması ile gözenek oranının
azaldığı tespit edildi. Genel gözenek oluşumunun açık ve kapalı gözeneklerden
meydana geldiği, farklı ebatlarda gözenek-lerin varlığı görüldü.

Keywords
