For inducing form memory effects of FMEs, at least one deformation of the alloy is required. Traditionally, it is carried out at room temperature or in liquid nitrogen. The influence of the initial phase composition on different schemes of FME and OEPF guidance has been studied. The evolution of reversible and complete reversible deformation, depending on the induced deformation, has an extreme character, while the position of the maximum depends on the structural state: for an equiatomic alloy Ti-50.0 at.% Ni - range εt = 1215%; for Ti-50.7 at.% Ni.

Effect Of Socioeconomic Factors On Kentucky Truck Driver Crashes, Nikiforos Stamatiadis, Shraddha Sagar, Samantha Wright, Aaron Berry Cambron
Kentucky Transportation Center Research Report
Kentucky crash data for the 2015-2016 period reveal that per capita crash rates and increases in crash-related fatalities in the state outpaced the national average. To explain why the U.S. Southeast sees higher crash rates than other regions of the country, previous research has argued the region’s unique socioeconomic conditions provide a compelling explanation. Taking this observation as a starting point, this study uses an extensive crash dataset from Kentucky to examine the relationship between highway safety and socioeconomic and demographic characteristics. Its focus is single- and two-unit crashes that involve commercial motor vehicles (CMVs) and automobiles. Using binary logistic …
