TL;DR: In this paper, the effects of gravity on colloidal crystallization were investigated on the microgravity experiments performed on the Space Shuttle Columbia and the results showed that the f.h.c.p. component may be induced by gravity-induced stresses.

TL;DR: In this paper, a combined experimental and theoretical investigation of the transformation temperature and transformation strain behaviors of a promising new Ni_(50.3)Ti_(29.7)Hf_(20) high-temperature shape memory alloy was conducted.

TL;DR: In this article, a linear stability analysis of the Ackerson and Schatzel model for crystallization of hard spheres was performed and the relationship between hard sphere and molecular crystal growth was exploited to relate the predicted linear instability to the well-developed dendrites observed.

TL;DR: In this paper, the effect of bulk composition on basic microstructural parameters, including solvus, volume fraction, topologically close-packed (TCP) phases, γ and γ′ phase chemistries, and lattice mismatch were investigated.

TL;DR: In this article, the phase diagram of colloidal hard spheres is measured in microgravity avoiding the effects of sedimentation and convection that arise with normal gravity, and for high concentration samples near random close packing, no evidence for a glassy phase.
