Effect of shrinkage porosity on mechanical properties of ferritic ductile iron

better properties combination 24-34 , such as high mechanical strength, excellent fracture toughness, good H 2 S resistance, reduction of the Bauschinger effect and superior fatigue

Analysis of the chemical composition, hardness and wear tests showed that the effect of bead overlapping on coating features is most pronounced in the first and second beads.

One poured specimens of the investigated alloy in the following conditions: without vibrations, with 50%ampliture of the vibrations (0,4 mm), with 100% amplitude of the vibrations

Results of investigations of influence of small vanadium up to 0.3%, niobium up to 0.16% and nitrogen up to 58 ppm additions and heat treatment of 1080 o C-24h/640 o C and 1080

Descriptive statistics for measuring the surface area the primary precipitates of intermetallic phases IM_W\ κ I (Sap_IM_W\ κ I, μ m 2 ) depending on the annealing time ( τ _ia,

Basing on the results of MANOVA test it has been observed that the strongest significant effect on an increase of the tensile strength R m exerted the addition of Mg, followed by

The higher the fraction of solid phase in the partly solidified melt during pouring, the poorer the mechanical properties of thixocast components.. The solid fraction decreases as

The effect of heating temperature during the heat treatment processes and quenching media on the tensile strength , percentage of elongation , hardness,
