Optimization of Thermo-Mechanical Processing for Forging of Newly Developed Creep-Resistant Magnesium Alloy ABaX633
The compressive strength and creep resistance of cast Mg-6Al-3Ba-3Ca (ABaX633) alloy has been measured in the temperature range of 25 to 250 ◦C, and compared with that of its predecessor ABaX422. The alloy is stronger and more creep-resistant than ABaX422, and exhibits only a small decrease of yield stress with temperature. The higher strength of ABaX633 is attributed to a larger volume fractio...
متن کاملForging Ahead
Editorial Forging Ahead 'All I know,' wrote Seamus Heaney, 'is a door into the dark 1 .' Me too. The world of radiology is figuratively and perhaps, on occasion, literally just that. Our game is the image, not the written word. Pretty pictures. Yet, now we increasingly find ourselves integral to the medical paradigm. This, clearly, is no reflection on us, but underpins the requirement, primacy,...
متن کاملPrediction of forging force and barreling behavior in isothermal hot forging of AlCuMgPb aluminum alloy using artificial neural network
In the present investigation, an artificial neural network (ANN) model is developed to predict the isothermal hot forging behavior of AlCuMgPb aluminum alloy. The inputs of the ANN are deformation temperature, frictional factor, ram velocity and displacement whereas the forging force, barreling parameter and final shape are considered as the output variable. The developed feed-forward back-prop...
متن کاملForging the Dream
Studies that examine spatial character-istics of urban unemployment are oftenbased on some simplistic and problematicmeasures of employment accessibility. Thispaper presents a refined methodologicalframework for measuring accessibility,which enables the researcher to (1) improvethe measurement by accounting for job com-petition among workers commuting by dif-...
متن کاملForging freedom from fear.
Date Received: 25 September, 1997 Accepted: 12 December, 1997 Introduction Before I expose my subject, I would like to pay tribute to the memory of Dr. Brock Chisholm, first Director-General of the World Health Organization, whose memory inspired the establishment of this lecture. Those who did so obviously hoped to create a chain of inspiration leading from the root of the Organization into th...
