Blue Brittleness 2

(english) Reduced ductility occurring as a result of strain aging, when certain ferrous alloys are worked between 300 and 700 (degrees) F. This phenomenon may be observed at the working temperature or subsequently at lower temperatures.

Total suspended solids

(Environmental Engineering) (TSS) is the amount of suspended (filterable) matter in a water.

Age Hardening

(english) Hardening by aging, usually after rapid cooling or cold working. The term as applied to soft, or low carbon steels, relates to a wide variety of commercially important, slow, gradual changes that take place in properties of steels after the final treatment. These changes, which bring about a condition of increased hardness, elastic limit, and tensile strength with a consequent loss in ductility, occur during the period in which the steel is at normal temperatures.

Neat Cement

(Concrete Engineering) Unhydrated hydraulic cement.

Calcium Aluminate Cement

(Concrete Engineering) The product obtained by pulverizing clinker consisting essentially of hydraulic calcium aluminates resulting from fusing or sintering a suitable proportioned mixture of aluminous and calcareous materials.

regular maintenance

การบำรุงรักษาปกติ : ดู [[maintenance]], [[regular]]

Department

กรม, ทบวง, กอง, (ในส่วนราชการ) Depratment of Lands = กรมที่ดิน Department of Land Co-operatuve = กรมสหกรณ์ที่ดิน Department of Mines = กรมโลหะกิจ Department of Public and Municipal Works = กรมโยธาเทศบาล Department of State Higways = กรมทางหลวงแผ่นดิน

Acid-Brittleness

(english) Brittleness resulting from pickling steel in acid; hydrogen, formed by the interaction between iron and acid, is partially absorbed by the metal, causing acid brittleness.

acetylene generator

(การเชื่อมต่อ) ท่อหรือหลอดบรจุแก๊สเชื่อมโลหะ ซึ่งมีความอัดดันสูง ปฏิกิริยาของน้ำกับ calcium carbide เป็นตัวการทำให้เกิด acelyiene gas

Moment:

(english) The resultant of a system of forces causing rotation without translation. A moment can be expressed as a couple.

Addition Agent

(english) 1) Any material added to a charge of molten metal in bath or ladle to bring alloy to specifications, 2) reagent added to plating bath.

Keene's Cement

(Concrete Engineering) A finely ground high density plaster composed of anhydrous, (calcined or "dead burned") gypsum, the set of which is accelerated by the addition of other materials.
