Yield Strength Requirements S2. The most widely accepted method of measuring the material ductility factor of susceptibility to lamellar tearing is the aastm of area of a round tension test specimen oriented perpendicular to the rolled surface of a plate.
Within the text, the SI units are shown in brackets. Click Here to join Eng-Tips and talk with other members! Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.
ASTM A770/A770M – 03(2012)E1
Two tests shall be required from each quenchedand-tempered plate. The number of tests required will depend upon the thickness of the plate being tested and the reduced section length selected.
This specification covers procedures and acceptance standards for the determination of reduction of area using steel plates as tension test specimen. Because of the effect of inclusions on the fracture process, the appearance of the? This standard is subject to revision at any time by asttm responsible technical committee and must be reviewed every? Further strain can cause the remaining metallic ligaments to shear or rupture, resulting in the step-like fracture appearance.
Are you an Engineering professional? A Test Methods a707 De? However, unless the order speci? Promoting, selling, recruiting, coursework and thesis posting is forbidden.
Reduction of Area Requirements S3. For plates over 6 in. Several types of test specimen shall have specified values of plate thickness, diameter, minimum radius, and length of reduced section. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other.
Last previous edition approved in as A — 86 Register now while it’s still free! See Test Methods and De? Below this minimum value, the reduction at the failure point in the reduced section is restrained by the larger cross section away from the reduced section. For example, those nonmetallic inclusions that form during the solidi? The joining method used shall be one which results in a minimal heat-affected zone in the portion of the plate to be tested.
Historical Version s – view previous versions of standard. The principal purpose of the testing is to provide a measure of the resistance of a steel plate to lamellar tearing. To provide a high resistance to lamellar tearing may require the use of special steel-making processes that can reduce the oxygen and sulfur contents in the steel to very low levels.
Because these relationships between the test specimen diameter and the average and variability of the test result have not been satisfactorily quanti? The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other.
The Type A aa770 provides a reduced section length greater than the plate thickness. Reasons such as off-topic, duplicates, flames, illegal, vulgar, or students posting their homework.
The intent of this speci? Originally approved in A minimum slenderness ratio of 2.

It is generally caused by wstm induced in the thickness direction resulting from shrinkage of the weld deposit and by the restraint imposed by the components that comprise the weldment. For Type 3 specimens, locate the weld fusion line of one plate surface within 1?
It is also accepted that smaller diameter test specimens will tend to give greater variability to the resulting reduction in area values. The tension testing method shall provide a measure of the resistance of a steel plate to lamellar tearing.
