In the present study, a new type of Ti-Mg/AZ91 composite has been successfully manufactured using pressureless infiltration method to be used for structural and functional applications. Porous Ti6Al4V alloy skeleton structure was produced by loose powder sintering which was then filled with either liquid magnesium or AZ91 alloy at around 800 qC under high purity argon atmosphere in order to obtain Ti-Mg composites. Starting porous preforms contained 40 vol% open porosity, and nearly all of the pores were co...
Production and characterization of aluminum matrix composites for small-scale unmanned aircraft engine pistons
Demiralp, Muammer; Kalkanlı, Ali; Department of Metallurgical and Materials Engineering (2020)
The composite materials are used in every stage in life, from the aerospace industry to agriculture. In most composites, the primary purpose of adding reinforcement to the matrix material is to increase the strength and stiffness of the matrix. Nowadays, most engineering materials are replaced with the composite materials due to higher specific strength. In this study, particle reinforced metal matrix composite is used to produce pistons for a small-scale unmanned aircraft engine. Conventional pistons are p...
Production and characterization of porous titanium alloys
Esen, Ziya; Bor, Şakir; Department of Metallurgical and Materials Engineering (2007)
In the present study, production of titanium and Ti6Al4V alloy foams has been investigated using powder metallurgical “space holder technique” in which magnesium powder were utilized to generate porosities in the range 30 to 90 vol. %. Also, sintering of titanium and Ti-6Al-4V alloy powders in loose and compacted condition at various temperatures (850-1250oC) and compaction pressures (120-1125 MPa), respectively, were investigated to elucidate the structure and mechanical properties of the porous cell walls...
Production and characterization of yttria stabilized zirconia ceramic blocks for dental applications
Kaplan, Melis; Öztürk, Abdullah; Park, Jongee; Department of Metallurgical and Materials Engineering (2017)
Dense zirconia ceramic blocks were produced by pressureless sintering at temperatures down to 1350- 1450 oC for dental applications. The effect(s) of integration of cold isostatic pressing (CIP’ing) to the production procedure of the zirconia blocks was researched by applying 80, 100, and 150 MPa isostatic pressure. The effect of color infiltration solutions (NiCl2 and MoCl3 solutions) on color and low temperature degradation properties of zirconia was investigated. Tetragonal to monoclinic phase transforma...
