Abstract

Within the scope of this study, Laser Cladding of Inconel 718 powder was applied on AISI 1050 fabrication steel. During this process, to analyze the effect of dispersion on mechanical properties, an empirical study was carried out on the samples produced at the relevant parameters. The results show high deviations for breaking stress and ductility. This distribution is due to the presence of porosity in the deposited material. Also, the best results were obtained from the samples in the central region, while the tests performed on the samples from the outer regions showed lower values for breaking stress and ductility. In addition, when the hardness values were examined, it was seen that the heat-affected area was harder than the base material and this was due to the cooling rate of the heat-affected area. In addition, the Laves phase was found to be the main cause of the generation of micro-voids that lead to fracture over time.

Özet

Bu çalışma kapsamında, Inconel 718 tozunun AISI 1050 imalat çeliği üzerine lazerle dolgu kaynağı işlemi uygulandı. Bu işlem sırasında, dispersiyonun mekanik özellikler üzerindeki etkisini analiz etmek için, ilgili parametrelerde üretilen numuneler üzerinde ampirik bir çalışma gerçekleştirildi. Sonuçlar, kopma gerilmesi ve süneklik için yüksek sapmalar olduğunu göstermektedir. Bu dağılım, biriken malzemede gözenekliliğin varlığından kaynaklanmaktadır. Ayrıca, en iyi sonuçlar merkez bölgedeki numunelerden alınırken, dış bölgelerden alınan numuneler üzerinde yapılan testler kopma gerilmesi ve süneklik için daha düşük değerler göstermiştir. Bunun yanında sertlik değerleri incelendiğinde ısıdan etkilenen bölgenin ana malzemeden daha sert olduğu ve bu da ısıdan etkilenen bölgenin soğuma hızından kaynaklandığı görülmüştür. Buna ilaveten de Laves fazı, zamanla kırılmaya yol açan mikro boşlukların üretilmesinin ana nedeni olduğu anlaşılmıştır.
