GÖZENEKLİ NiTi ŞHA’IN TOZ METALURJİSİ İLE ÜRETİMİ VE ÖN ISITMA SICAKLIĞININ GÖZENEK OLUŞUMU ÜZERİNDEKİ ETKİSİ

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.
