The mechanical behavior of low (and negative) thermal expansion and low stiffness Al2TiO5 materials and Al2TiO5–3Al2O3.2SiO2–ZrTiO4 composite materials was studied by diametral compression test at room temperature 400 and 800°C. The effect of both temperature and composition was analyzed. Stress–strain curves were obtained and, from them, apparent elastic modulus (Eapp) and mechanical strength (σF...
