ON THE CREEP DEFORMATION OF A CAST NEAR GAMMA TiA1 ALLOY Ti -48Al - lNb
-The steady-state creep deformation behavior of a cast two phase gamma TiA1 alloy having the composition Ti-48AI 1Nb (a t . ° ) has been studied. Tension creep tests using the stress increment technique (a~ < cr 2 < or3) were conducted over the temperature range of 704-850°C at constant initial applied stress level of 103.4-241.3 MPa. The activation energy for creep over the temperature and str...
متن کاملThe microstructure of plasma arc cold-hearth melted Ti-48Al-2Mn-2Nb
The purpose of this paper is to show the results of some work at the IRC in Materials for High Performance Applications at the University of Birmingham into the effect of processing and process parameters on the microstructure, macrostructure and chemistry of 100 mm diameter single plasma-melted ingots of a gamma-based titanium aluminide (Ti-48at%Al-2at%Mn-2at%Nb). The microstructure of the aqm...
متن کاملMicrostructure Stability and Creep Strength in a Die-Cast AX52 Magnesium Alloy
Superior creep strength of a heat resistant AX52 magnesium alloy is ascribed to the grain boundary eutectic Al2Ca phase covering the primary -Mg grains. The eutectic phase is stable in morphology at temperatures below 473K, while it collapses during long term exposure at temperatures higher than 473K. The microstructural change of the alloy during high temperature exposure is characterized by t...
متن کاملThe Microstructure, Creep, and Tensile Behavior for Ti-5Al-45Nb (Atomic Percent) Fully-b Alloy
The microstructure, tensile, and creep behavior of a Ti-5Al-45Nb (at. pct) alloy was evaluated. The main objective of processing and characterizing this alloy was to obtain the constituent properties of a fully-b Ti-Al-Nb alloy to aid in modeling the tensile and creep properties of twophase orthorhombic + body-centered-cubic (O + bcc) alloys. A second objective was to compare the tensile and cr...
متن کاملTHE EFFECT OF SEVERE PLASTIC DEFORMATION ON THE MICROSTRUCTURE AND MECHANICAL PROPERTIES OF AS-CAST AZ31
The evolution of microstructure and mechanical properties of a magnesium cast alloy (AZ31) processed by equal channel angular pressing (ECAP) at two different temperatures were investigated. The as-cast alloy with an average grain size of 360 was significantly refined to about 5 after four ECAP passes at 543 K. Grain refinement was achieved through dynamic recrystallization (DRX) du...
