Additive Manufacturing at PM Titanium 2015<br />
Developments in the Additive<br />
Manufacturing of titanium at<br />
PM Titanium 2015<br />
The PM Titanium 2015 conference, held in Lüneburg, Germany,<br />
from August 31 to September 3, 2015, was the latest in the series<br />
of international conferences specifically focused on the processing,<br />
consolidation and metallurgy of titanium. As Dr David Whittaker<br />
reports for Metal Additive Manufacturing magazine, the ambition to<br />
apply titanium AM components in critical applications continues to<br />
drive researchers to further understand the influences of processing<br />
parameters on achieved microstructure and on the relationships<br />
between microstructure and mechanical properties.<br />
PM Titanium 2015, the third in the<br />
international series of conferences<br />
on Powder Processing, Consolidation<br />
and Metallurgy of Titanium, was<br />
held at the Leuphana University in<br />
Lüneburg, Germany, from August 31<br />
to September 3, 2015. The conference<br />
attracted an attendance of over 130<br />
delegates from 27 countries. Encouragingly<br />
for an area of technology<br />
where, to date, the high level of R&D<br />
activity has not yet been matched<br />
by significant market penetration,<br />
several delegates from potential endusers<br />
were present, representing the<br />
aerospace, biomedical and consumer<br />
products sectors.<br />
Within the ten technical session<br />
programme, two sessions were<br />
devoted specifically to the Additive<br />
Manufacturing of titanium and<br />
relevant papers also appeared in<br />
other sessions. This article reviews<br />
selected papers from the programme,<br />
all related to the processing of<br />
Ti-6Al-4V.<br />
A consideration which is of high<br />
significance with regard to the viability<br />
of the use of Additive Manufacturing<br />
for safety-critical applications is the<br />
development of robust knowledge on<br />
the influences of processing parameters<br />
on achieved microstructure<br />
and on the relationships between<br />
microstructure and mechanical<br />
properties.<br />
The reviewed papers all touch on<br />
this consideration by addressing the<br />
development of numerical simulation<br />
approaches to the modelling of the<br />
phase transformations as the melt<br />
pool is cooled during the Selective<br />
Laser Melting (SLM) process, the<br />
influence of post-build heat treatment<br />
