There are six main hardness tests that can be carried out.

. 316 Hardness is best defined as which one of the following. Water is the most important compound that is needed for the survival of life on earth. Increase fluidity and lowers melting temperature.

Hardening is carried to accomplish the following. Energy absorbed by a material when an object strikes its surface. 2310 Tempering is a heat treatment applied to hardened steels that is best defined as which of the following one correct answer.

This is a Most important question of gk exam. To reduce the grain size. C hardened tool steel.

Resistance to permanent indentation. Macroscopic hardness is generally. You should consider the hardness range of the specimen you want to test before choosing a hardness tester.

Hardness of metals is best defined as which one of the following an increased tensile strength and a decreased ductility Plastically deforming a metal specimen near room temperatures generally leads to which of the following properties. Hardness below these levels can be tested by using penetrators made from steel or other similar hard metals. In geology a mineral is defined as.

Aggregates of one or more minerals. Hardness is a measure of the resistance to localized plastic deformation induced by either mechanical indentation or abrasion. A energy absorbed by a material when an object strikes its surface b resistance to bending c resistance to permanent indentation or d resistance to scratching.

The hardness of water is due to the presence of soluble bicarbonates chlorides and sulfates of calcium and magnesium. A amount by which the die islarger than the punch b amount of elastic recovery experienced by the metal after bending csafety factor used in calculating bending force or d length before bending of the straight sheetmetalsection to be bent. Which one of the following best defines hardness.

Generally if the hardness of the specimen is above 650 HB30 then you should use a diamond penetrator. Vickers Rockwell Brinell Mohs Shore and Knoop. Water which does not give lather with soap is hard water.

More simply put when using a fixed force load and a given indenter the smaller the indentation the harder the. Hardness is defined as the resistance to indentation of a material. The cohesion of the particles on the surface of a mineral as determined by its capacity to scratch another or be itself scratched.

Which one to apply depends on the type of material to be tested and the equipment available. Most hardness tests involve pressing a hard object into the surface of a test specimen and measuring the indentation that results. Which one of the following types of stress strain relationship best describes the behaviour of brittle materials such as ceramics and thermosetting plastics.

Softens iron and increase ductility below 325 hardens iron above 325 and increase acid and corrosion resistance above 13. To increase the wear resistance of Steel. Hardness is not a material property rather a value ascribed to a material as a result of empirical testing.

A heating and soaking at a temperature above the austenitizing level followed by rapid cooling b heating and soaking at a temperature above the austenitizing level followed by slow cooling c heating and soaking at a temperature below. Which one of the following materials has the highest hardness. It is tested by pressing a hard object into the test material and measuring the size of the indentation.

Which one of the following materials has the highest hardness. Deoxidizes molten cast iron. Hardness is best defined as which one of the following.

Improve the magnetizing properties. D high carbon steel. In general different materials differ in their hardness.

Hardness is best defined as which one of the following Resistance to permanent indentation Most hardness tests involve pressing a hard object into the surface of a test specimen and measuring the resulting indentation or its effect. It is defined as the resistance to indentation and it is determined by measuring the permanent depth of the indentation. A energy absorbed by a material when an object strikes its surface b resistance to bending c resistance to permanent indentation or d resistance to scratching.

Formulating a more rigorous definition of hardness is difficult because any test method will at a microscopic level involve complex surface morphologies and stresses in the test material thereby involving a variety of qualities in any single hardness test. 208 Which one of the following is the best definition of bend allowance. Hardness may be broadly defined as the resistance to permanent surface indentation or penetration.

Reduce ductility to the minimum. Hardness is a characteristic of a material not a fundamental physical property. Which one of the following materials has the highest hardness.

Hardness of Water - Temporary and Permanent Hardness in Water. A naturally occurring usually inorganic solid consisting of chemical elements in specific proportions whose atoms are arranged in a systematic internal pattern. Reduce hardness by combining with sulfur below 05 and increase the hardness above 05.

The strength and hardness of the Steel are increased but makes it more brittle since ductility is reduced. For example hard metals such as titanium and beryllium are harder than soft metals such as sodium and metallic tin or wood and common plastics. B gray cast iron.
