hard strata

Beryllium Copper

แปลว่า(english) An alloy of copper and 2-3% beryllium with optionally fractional percentages of nickel or cobalt. Alloys of this series show remarkable age-hardening properties and an ultimate hardness of about 400 Brinell (Rockwell C43). Because of such hardness and good electrical conductivity, beryllium-copper is used in electrical switches, springs, etc.

Resources

แปลว่า(Software Engineering) anything that is required to get the project done, people, hardware, materials, information, etc.

Hardware

แปลว่าเครื่องเหล็ก, เครื่องโลหะ [ช่างก่อสร้าง]; ฮาร์ดแวร์ [คอมพิวเตอร์]; ส่วนอุปกรณ์ [วิชาถ่ายภาพ]; ส่วนเครื่อง, ส่วนอุปกรณ์ [การพิมพ์ ]

Black Oil Tempered Spring Steel Strip (Scaleless Blue)

แปลว่า(english) A flat cold rolled usually .70/.80 medium high carbon steel strip, blue-black in color, which has been quenched in oil and drawn to desired hardness. While it looks and acts much like blue tempered spring steel and carries a Rockwell hardness of C44/47, it has not been polished and is lower in carbon content. Used for less exacting requirements than clock spring steel, such as snaps, lock springs, hold down springs, trap springs, etc. It will take a more severe bend before fracture than will clock spring, but it does not have the same degree of spring-back.

hardpan

แปลว่าชั้นดินแข็งใกล้ผิวดิน (เกิดจากการเชื่อมยึดประสานด้วยแร่เหล็ก หรือเกลือแคลเซียม)

Boron (chemical symbol B)

แปลว่า(english) Element N. 5 of the periodic system. Atomic weight 10.82. It is gray in color, ignites at about 1112 (degrees) F. and burns with a brilliant green flame, but its melting point in a non-oxidizing atmosphere is about 4000 (degrees) F. Boron is used in steel in minute quantities for one purpose only- to increase the hardenability as in case hardening and to increase strength and hardness penetration.

Bronze

แปลว่า(english) An alloy containing 90% copper and 10% tin. Used for screws, wire, hardware, wear plates, bushings and springs; it is somewhat stronger than copper and brass and has equal or better ductility.

Bake

แปลว่า(english) Heat in an oven to a low controlled temperature to remove gases or to harden a binder.

Rock Pocket

แปลว่า(Concrete Engineering) Area or portion of hardened concrete which is deficient in mortar and consisting primarily of coarse aggregate and open voids; caused by insufficient consolidation or separation during placement, or both; by leakage from form.

hard water

แปลว่าน้ำกระด้าง
