Boron Steels

(english) The addition of boron in the range 0.0005-0.005% to certain steels increases the hardenability. A range of boron steels is now listed in the current BS 970 and are widely used for the production of cold headed fastenings.

apron frange

ชาย (กระเบื้อง) หรือปีกที่ยื่นออกมาเป็นกระบัง

chromiun-orange

สีส้มที่ทำจากโครเมี่ยม

Particle-Size Distribution

(Concrete Engineering) Particle distribution of granular materials among various sizes; for concrete material normally designated as gradation. Usually expressed in terms of cumulative percentages smaller or larger than each of a series of sieve openings or percentages between certain ranges of sieve openings.

osage orange

(ไม้) ชื่อไม้มีทั้งขนาดเล็ก และขนาดกลาง เป็นไม้มีลายเหลือง และแดง แข็งแรงและทนทาน ใช้ทำไม้ตะบองตำรวจ, เสารั้ว, คันธน ฯลฯ

range screw

เกลียวตั้งระยะเริ่มเดินเครื่อง

Colloids

(Environmental Engineering) Small particles which have a negligible settling velocity. These particles have a very small mass so gravitational force is low compared to surface frictional forces. Typical colloidal sizes range from 10-3 mm to 1 mm.

Gillmore Needle

(Concrete Engineering) A device used in determining time of setting of hydraulic cement, described in ASTM 0 266. Gradation The sizing of granular materials; for concrete materials, usually expressed in terms of cumulative percentages larger or smaller than each of a series of sieve openings or the percentages between certain ranges of sieve openings.

Box Annealing

(english) Annealing a metal or alloy in a sealed container under conditions that minimize oxidation. In box annealing a ferrous alloy, the charge is usually heated slowly to a temperature below the transformation range, but sometimes above or within it, and is then cooled slowly; this process is also called close annealing or pot annealing.

Blue Brittleness

(english) Brittleness exhibited by some steels after being heated to some temperature within the range of 300 (degrees) to 650 (degrees) F, and more especially if the steel is worked at the elevated temperature. Killed steels are virtually free of this kind of brittleness.

Break Test (for tempered steel)

(english) A method of testing hardened and tempered high carbon spring steel strip wherein the specimen is held and bent across the grain in a vice-like calibrated testing machine. Pressure is applied until the metal fractures at which point a reading is taken and compared with a standard chart of brake limitations for various thickness ranges.

orange lead

(เคมี) ตะกั่วเหลือง ( Pb3O4) ได้จากการเผาตะกั่วขาว ในอุณหภูมิประมาณ 450 C.
