Dispersion Strengthened Titanium Alloys

Finley dispersed nano-particles of oxides can be successfully used in the strengthening of titanium alloys due to their hardness, stability and insolubility in the base-metal.
Other dispersoids can also be used such a ceramics but the most important aspect is for them to be thermodynamically stable, homogeneously distributed in the metal matrix and of nanometric size. Continue reading

Corson Alloys

Corson or Corson bronze is a copper nickel silicon system which maintains the most fundamental advantages of copper alloys i.e. excellent conductivity, whilst providing adequate mechanical and physical properties to be considered for industrial applications.
Significant advancement of these alloys occurred over time and as the grain size and microstructure were adjusted to provide superior property profiles from the Cu–Ni–Si alloys. Continue reading

High Boron Cast Iron: Part One

Boride emerged as a good alloying option for iron based alloys to help improve toughness and specifically help in applications where wear resistance is important.
The addition of boron causes martensite transformation to a mixed state with austenite and this provides the platform for improved overall toughness in the material. Continue reading
