Cryogenic Treatment of Stainless Steels

Cryogenic treatment of stainless steels is just one method that can be used to reduce commonly occurring microstructural defects in stainless steels.
With cryogenic treatment the general strength properties of stainless steels can be improved and with the additional heat treatment, plasticity can also be effectively preserved. Continue reading

High Boron Cast Iron: Part Two

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.
There are many studies available but here we discuss the effect of different tempering temperatures on the microstructure and mechanical properties of high boron white cast iron after air quenching. Continue reading

Adhesive Bonding

One of the earliest and most recognized adopters of adhesives to join metal parts was the aircraft industry who began using the available technologies during World War II.
Nowadays adhesive bonding is a commonly used technique for joining similar and dissimilar materials and whilst if offers great flexibility in design, the mechanics of the joints must be well understood. Continue reading

Iron Spark Plasma Sintering: Part Two

Spark Plasma Sintering (SPS) is a sintering technique which is well matched to mechanically milled materials such as tool steels due to its low temperature and short cycle time.
One of the key objectives using SPS is to increase the density of the sinter in order to attain better overall property profiles of the finished part. Continue reading

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

FASTMET Iron Processing

The FASTMET process was developed in the 90’s by several key industry players to create a more cost effective iron making process to combat rising natural gas prices which fueled more established processing in place since the 60’s.
The FASTMET process is simple and unique and involves rapid heating which in turn accomplishes a rapid reduction reaction. Continue reading

Dispersion Strengthened Copper Alloys: Part Two

Coppers range of advantageous characteristics a quite well known including high electrical and thermal conductivity, excellent corrosion resistance to name but a few.
Dispersion strengthened coppers add the advantage of higher strengths which means they can be used for a range or applications such as welding consumables. Continue reading
