... Greninger, was a pioneering investigation of the crystallography of the martensite transformation in steels. At a time when a fierce controversy was raging about the decomposition of austenite at low temperatures, Troiano and Greninger established unequivocally the essential and distinct kinetic behavior of the martensite transformation.

... Upon retirement from the Republic Steel chair in 1979, he remained active in research at Case Western Reserve University as senior research scientist and Republic Steel professor emeritus until his death on June 12, 2002. While at Case, he initiated programs in mechanical properties, with a focus on the metallurgical aspects of embrittlement, which led to programs in slack quenching and the end-quench test, 500°F embrittlement of quenched and tempered steels, the mechanical properties of carburized steels, hydrogen embrittlement and delayed failure, and eventually stress-corrosion phenomena.

... , who initiated a graduate project in ceramics, which, in the ensuing decades, played an important role in the evolution of ceramic science and technology in the United States. Professor Troiano published extensively on heat treatment and phase transformations of ferrous and nonferrous alloys, engineering applications of materials, and environmental degradation of materials, including hydrogen embrittlement and stress-corrosion cracking.

... His leadership, insight, and unselfish devotion were instrumental in the development of both strong research and curricular programs and the academic and professional development of aspiring young faculty. An entire generation of students, first at Notre Dame and then Case Institute of Technology and Case Western Reserve University, benefited from his guidance, his wise counsel, and his sympathetic concern.

From page 319...
... His achievements spanned the gamut from insights into the atomistic mechanisms of martensitic transformations and stress corrosion to applied industrial problems involving residual stresses. Being both a teacher and mentor to students and faculty, he cultivated critical thinking combined with a sense of practicality to the many people whose lives he influenced.
