“…Aluminum provides an increase in mechanical properties in Ni-Cr alloys by forming a hardening compound (Ni 3 Al), and C in concentrations from 1% to 3% significantly increases the hardness values and diminishes elongation. 15 Wiron-99 alloy showed low tensile strength and microhardness values, but higher elongation values. These values can be explained when one observes the composition of this alloy, which contains elements with high solubility, such as Cr, Mo and Nb, 10 in the Ni matrix.…”

The aim of the present study was to evaluate the tensile strength, elongation, microhardness, microstructure and fracture pattern of various metal ceramic alloys cast under different casting conditions. Two Ni-Cr alloys, Co-Cr and Pd-Ag were used. The casting conditions were as follows: electromagnetic induction under argon atmosphere, vacuum, using blowtorch without atmosphere control. For each condition, 16 specimens, each measuring 25 mm long and 2.5 mm in diameter, were obtained. Ultimate tensile strength (UTS) and elongation (EL) tests were performed using a Kratos machine. Vickers Microhardness (VM), fracture mode and microstructure were analyzed by SEM. UTS, EL and VM data were statistically analyzed using ANOVA. For UTS, alloy composition had a direct influence on casting condition of alloys (Wiron 99 and Remanium CD), with higher values shown when cast with Flame/Air (p < 0.05). The factors 'alloy" and 'casting condition" influenced the EL and VM results, generally presenting opposite results, i.e., alloy with high elongation value had lower hardness (Wiron 99), and casting condition with the lowest EL values had the highest VM values (blowtorch). Both factors had significant influence on the properties evaluated, and prosthetic laboratories should select the appropriate casting method for each alloy composition to obtain the desired property.

“…The microhardness of Ni-Cr alloys used in fixed prosthodontics after casting under different conditions and the effect of casting technique on surface roughness and consequent mass loss after polishing of Ni-Cr and Co-Cr base metal alloys was investigated (Bauer et al, 2006;Bezzon et al, 2004). Influence of solute atoms on the surface roughness, microstructure, and mechanical properties (tensile strength and hardness) of Ni-Cr alloy was studied and correlated (Das et al, 2010). Also alloying with other elements is required to ensure the achievement of mechanical and corrosion resistance, castability and porcelain bonding (Bezzon et al, 1998;Baran, 1983).…”

Heat treatment is a process in which alloy is heated to get different microstructures and desired properties associated with it which may affect the corrosion rate, nature form and size. Effect of annealing on microstructure, creep indentation, hardness and electrochemical corrosion behavior of Ni63Cr24.6Mo10.8Si1.5Mn0.06C0.04 alloy were investigated. Microstructure of Ni63Cr24.6Mo10.8Si1.5Mn0.06C0.04 alloy changed after annealing at different temperature for two hours. Crystal size of nickel in matrix alloy increased after annealing for two hours at different temperature. Stress exponent, n, Vickers hardness and calculated maximum shear stress of Ni63Cr24.6Mo10.8Si1.5Mn0.06C0.04 alloy decreased after annealing. Corrosion rate of Ni63Cr24.6Mo10.8Si1.5Mn0.06C0.04 alloy increased after annealing for two hours at different temperature.
