چکیده

The segregation of Alloy 718 ingots and the technical factors which affect the ingot homogenization practice are studied in this paper. The segregation and melting point of Alloy 7 18 ingots are studied by DTA, electron microprobe and structure analysis. The elimination of Laves phase is studied in detail. After the solution of Iaves phase the segregation elimination of Nb is reviewed further. Through the investigation an optimum homogenization treatment to eliminate the segregation of Alloy 7 18 ingots is proposed. Furthermore, the affection of deformation on homogenization practice of Alloy 718 ingots has been also studied.

Effect of Cooling Rate on Microstructural Development in Alloy 71 8 A

A variety of cast pyrometR 718 alloy microstructures result from processing of different diameters of industrial scale ingots for producing superalloy forgings used in aircraft turbine engine applications. The hot workability of these cast alloys will significantly depend on the cast microstructure. The current study is focussed on understanding the evolution of the cast microstructure during V...

Influence of Homogenization on Mechanical Properties of Al-1Mn-1Mg Alloy Prepared by Different Melt-Treatments

Influence of homogenization on mechanical properties of Al-1Mn-1Mg alloy prepared by different melttreatments was discussed and mechanism of metallurgical defects on ingots’ mechanical properties was analyzed. It was found that metallurgical defects, such as the inclusions and gas holes, cannot be removed from the original ingots by homogenization; the average increasement of tensile strength o...

Flow Behavior of SP-700 Titanium Alloy During Hot Tensile Deformation in α+β and β Phase Regions

In this paper, in order to study the flow behavior and elongation of as-cast ingots of SP-700 titanium alloy, hot tensile test was done in α/β dual phase and β single phase regions using strain rate of 0.1 s-1. Results showed that the hot tensile behavior of SP-700 in the α/β dual phase region (700-900 ºC) was different from the β single phase one (950-1100 ºC) due to the nature of alpha and be...

Fatigue and Anisotropic behaviours of cold rolled AA1200 Aluminium Alloy

This study examines the fatigue and anisotropy behaviour of cold rolled AA1200 aluminium alloy for light weight automotive connecting rod application. Aluminium (Al) 1200 ingots were melted at temperature of 680 0C (after one hour of heating) cast in sand mould and cast samples homogenized for 6 hrs at 480 0C. The cold rolling process was carried out after homogenisation for 10, 20, 30, 40 and ...

Experimental Investigation of Thermal Conductivity of Aluminum Alloy 3003 Produced by Equal Channel Angular Rolling Process

Equal channel angular rolling (ECAR) process is one of the methods that have been used to make ultra-fine materials by imposing severe plastic deformation. After repeating the process several times, a large effective strain is applied to the sample that can cause decreasing the grain size and improving the mechanical and physical properties of the metal. In this study, thermal conductivity of t...
