title: Comparison of blended elemental (BE) and mechanical alloyed (MA) powder compact forging into Ti-6Al-4V rocker arms

authors: Jia, Mingtu

subjects: Powder compact forging

abstract: Ti-6Al-4V rocker arms for internal combustion engines were produced by forging of compacts of blended powder consisting of elemental hydride-dehydride (HDH) titanium powder and Al60V40 (wt%) master alloy powder or mechanical alloyed (MA) powder synthesized by high energy mechanical milling of a mixture of HDH titanium and Al60V40 master alloy powders. The powder compacts were made by warm compaction, and their relative density was 90%. The mechanical properties and microstructures of as-forged parts made using blended powder were improved significantly with increasing holding time at forging temperature, and close to those of as-forged parts produced by powder compact forging of HDH Ti-6Al-4V pre-alloyed powder. However, the as-forged part produced by powder compact forging of MA powder was brittle, and fractured prematurely during tensile testing.

abstract: Ka maumahara tonu tatou ki a ratou - we will remember them…poignant last words…   bidding farewell to a generation of veterans moving on...leaving fragments  of memories and diaries for children/grandchildren to honour, celebrate and remember …black costumes billow, fold, swirl and wrap the dancers bodies…wide sweeping arm movements…jumps and turns…slides on all fours - provides the vehicle for five accomplished dancers to fill the space with fluidity and lyricism in this very moving finale, a lament set to Albinoni’s adagio - maybe old soldiers never die.
