NiTi Alloys for Structural and Tribological Applications:
The Other Side of Superelastics
Christopher Dellacorte
NASA Glenn Research Center
Nickel-rich alloys have been shown to be
amenable to advanced powder metallur-
gy processing, leading to a new class of
structural materials suited for challenging
tribological applications. Dellacorte will
introduce this new family of dimensionally
stable yet highly elastic materials and show
how NASA is putting them to work.
Control Property and Behavior of Nano-Structured Niti SMAs
by Grain Size Engineering
Qingping Sun
Hong Kong Univ. of Science and Technology
Grain size engineering holds promise as a
method for improving the performance of
shape memory alloys. Sun will report on
recent experimental and theoretical find-
ings that shed new light on the relationship
between grain size and the thermal, me-
chanical, cyclic, and fatigue properties of
NiTi SMAs.
Design of Supercompatible Shape Memory Alloys
Richard D. James
University of Minnesota
Supercompatibile SMAs can be opti-
mized for low thermal hysteresis with
multi-million cycle repeatability of full
transformation under high-stress su-
perelastic cycling. James will review
alloy design by supercompatibility and
how it relates to other alloy optimiza-
tion procedures based on the manipu-
lation of precipitates.
Breakthroughs and Misfortunes in the Maturing of NiTi
Medical Device Development
Brian Berg
Boston Scientific
Medical device engineers have method-
ical perseverance, learning from lim-
itations and mistakes to create better
devices. Berg will review real-life exam-
ples where breakthroughs in manufac-
turing, testing, deployment, and in vivo
use grew from failure.
Challenges towards Successful Integration and Test of
SMA Aerospace Applications
James H. Mabe
Boeing Research and Technology
Boeing’s successful flight tests in
2005 of Variable Geometry Chev-
rons on a 777 and the 2012 Adap-
tive Trailing Edge on a 737 clearly
demonstrated a high technology
readiness level for SMA actuator sys-
tems. Mabe will discuss the engineering, integration, and
program challenges, and how the flight test team over-
came them.
