Abstract
The temperature-dependent crack growth resistance behavior of the lead-free (1-x)Ba(Zr0.2Ti0.8)O-3-x(Ba0.7Ca0.3)TiO3 (x = 0.385) ceramic was characterized using compact-tension specimens from 25 degrees C to 60 degrees C. The observed plateau fracture toughness at 25 degrees C was found to be approximately 37% lower than commercial Pb(Zr,Ti)O-3. At elevated temperature, the maximum fracture toughness displayed a decrease, which was found to be related to the temperature-dependent elastic and ferroelastic properties. Mechanical measurements are presented that demonstrate decreasing effective switching strain, coercive stress and Young's modulus with increasing temperature. (C) 2015 Elsevier Ltd.
