Toz metal parçalar, yaygın avantajları nedeniyle birçok uygulamada kullanılmaktadır. İndüksiyon ile sinterleme hızlı bir sinterleme yöntemi olup, zaman ve enerji tasarrufu ve daha gelişmiş mekanik özellikler sağlaması sayesinde geleneksel sinterlemeye önemli bir alternatif bir proses olma yönünde ilerlemektedir. Bu çalışmada 600-800 MPa basınç altında çift eksenli presle beş farklı numune preslenmiştir. Numuneler geleneksel ve orta frekanslı (30 kHz) indüksiyon sinterleme mekanizması ile sinterlenmiştir. Numunelerin gövdesi doğrudan indüksiyon sinterleme yoluyla ısıtılmıştır. Geleneksel ve indüksiyon sinterleme yöntemleriyle üretilen numunelerin mekanik özellikleri ve mikroyapılarının karşılaştırılması yapılmıştır. Çalışma sonucunda kabul edilebilir mekanik özelliklerin elde edilmesinde indüksiyon ile sinterlemenin geleneksel sinterlemeye göre daha etkili bir işlem olduğu görülmüştür. Ayrıca indüksiyon ile sinterleme ile daha kısa işlem sürelerinde benzer mikroyapısal özellikler elde edilmiştir.

Investigation Of Induction Sinterability Of Powder Metal Parts Of Different Shapes And Sizes

Öz

Powder metal parts are used in many applications because of widely advantages. Induction sintering is a rapid sintering method, and it is moving towards to an important alternative process of conventional sintering by means of time and energy saving and more improved mechanical properties. In this study, five different samples were pressed with dual axis press under 600-800 MPa pressure. The samples were sintered with conventionally and with medium frequency (30 kHz) induction sintering mechanism. The body of the samples was heated directly by induction sintering. Comparison of the mechanical properties and microstructures of samples which produced by conventional and induction sintering methods were carried out. As a result of study, it was observed that induction sintering is more effective process in order to obtain acceptable mechanical properties than conventional sintering. Also, similar microstructural characteristics were obtained in shorter treatment times by induction sintering.
