Ductile Iron Data - Section 2

The presence of different carbides produced by alloying makes White Iron extremely hard and abrasion resistant but very brittle. Gray Iron As a result it is assumed by many to be the only form of cast iron and the terms "cast iron" and "gray iron" are used interchangeably.

Hardness Value - an overview ScienceDirect Topics

Transition metal carbides generally possess high values of Young& 39;s modulus 276–600 MPa . Most transition metals have values of 138–276 MPa. Carbides are generally very brittle at low temperatures. However at temperatures greater than or equal to 1000 C they undergo a brittle-to-ductile transition above which they plastically deform.

Use ductile in a sentence ductile sentence examples

Heat Treating Steel - Hardening and Tempering : Metalworking

To harden most steel it is heated to a medium red or slightly above the point where it becomes non-magnetic. It is then quenched in water oil or air depending on the type of steel. The steel is now at its maximum hardness but is very brittle. To reduce the brittleness the metal is tempered by heating it to some where between 350 F and 1350 F.

In its form tungsten is a hard steel-grey metal that is often brittle and hard to work. If made very pure tungsten retains its hardness which exceeds that of many steels and becomes malleable enough that it can be worked easily. It is worked by forging drawing or extruding but it is more commonly formed by sintering.

Tungsten in its pure form cannot be used in jewelry. Instead it is formed into a metal consisting of approximately 85% tungsten and 15% carbon nickel or cobalt which is known as tungsten carbide. Because tungsten is very brittle mixing it with carbon reduces this characteristic making the metal more durable and easier to work with.

Wrought Iron vs Cast Iron Metal Casting Blog

Cast iron is very brittle in nature meaning it’s comparatively hard and non-malleable. The final result is strong but brittle. Due to the higher carbon content cast iron solidifies as a heterogeneous alloy meaning it contains multiple constituents or materials in different phases within its microstructure.
