DAMPING CAPACITY AND MECHANICAL PROPERTIES OF Zn-Al ALLOY CASTINGS
This paper describes damping capac i t y and mechanical p roper t ies o f Zn-8-20%A1 and Zn-8-20%Al-0.02-0.04XMg a l l o y cast ings. Zn-8-20%A1 a l l o y casti ngs show h igh damping when quenched from 573K. Small amount o f Mg a d d i t i o n t o these a l l o y cast ings lowers damping capaci ty considerably b u t e f f e c t i v e t o reduce decomposition through aging a t 423K f o r 48hrs ...
متن کاملMechanical Properties and Spring -Back Investigation in Creep Age Forming Process of 7075 Al Alloy
Creep age forming (CAF) process is a novel metal forming method with major benefits including improved mechanical properties and cost reduction for aviation industry applications. CAF happens due to creep phenomenon and stress-release during the artificial aging of heat-treatable aluminum alloys. In this work, the creep age forming of 7075 Aluminum alloy at 120, 150 and 180 °C for 6, 24 and 48...
متن کاملEFFECT OF REFINING PROCESS ON POROSITY AND MECHANICAL PROPERTIES OF HIGH PRESSURE AL-SI ALLOY DIE CASTINGS
Abstract: This study presents the research results of effect that refining process has on porosity and mechanical properties of high pressure die castings made of AlSi12S alloy. The operation of refining was carried out in a melting furnace with the use of an FDU Mini Degasser. Mechanical properties (UTS, YS, Elongation, Brinell Hardness) were assessed on samples taken from high pressure die ca...
متن کاملSome Mechanical Properties of DTD 5025 Magnesium Alloy Castings 4 ’
SUMMARY This Report describes an investigation into the tensile and torsional properties of DTD 5025 magnesium alloy castings. Strength and stiffness values are given, and the variation of these parameters between different batches and manufacturers is shown. The effect on mechanical properties of long and short term temperature environments is mdwated.
متن کاملFatigue properties of Ni-43.5%Ti superelastic alloy castings.
To evaluate a Ni-43.5wt%Ti alloy as a new alloy for cast clasp, the fatigue properties of its castings were examined and compared with those of Co-Cr and Type IV Au alloys castings. The Ni-Ti alloy was cast into a phosphate-bonded investment mold using an argon-arc melting and pressure casting machine. The Ni-Ti alloy castings showed superelasticity in bending tests. Fatigue tests were carried ...
