evaluations of alloying effects on the kinetics and mechanisms of austenite decomposition and transformations in titanium-based alloys; the mechanical behavior of high-strength steels as related to slack-quenched structures and embrittlement during tempering; and the effects of hydrogen on the mechanical behavior of both ferrous and nonferrous alloys. The latter studies led to his interest, in the autumn of his career, in stress-corrosion cracking in a wide range of commercially important alloys.
The many honors he received and keynote lectures he presented at national and international conferences attest to his esteem in the metallurgical community. However, the many ways his contributions provided a conceptual framework for the evolution of the field is a more representative measure of the true value of his work. The list of his publications reveals his wide range of interests but gives no indication of the in-depth consultations, critical analyses, and probing discussions with colleagues, friends, and students that resulted in clarifications and the subsequent evolution of new concepts.
Throughout much of his career, Troiano’s immersion in research was paralleled by his attention to teaching and academic administration. 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.
Students who worked with Professor Troiano soon realized that his motivation for research was based on a deep-seated interest in industrial problems. In an era when many academic researchers were turning away from problems of interest to industry, he continued to devise and carry out research programs that clarified the basic metallurgical variables that controlled complex industrial processes and applications. His interest in industrial problems lasted throughout his career,
