تم في هذا البحث دراسة تأثير التقسية باستخدام التيارات عالية التردد على الخصائص الميكانيكية لنوعي الفولاذ الكربوني (0.59%C , 0.35%C) الأكثر استخداماً في عمليات التصنيع المحلي، حيث تم أخذ عينات من نوعي الفولاذ بعد تقسيتها بالتيارات عالية التردد عند قيم مختلفة للاستطاعة و لسرعة تحرك ملف التحريض و إجراء اختبارات القساوة و الشد و الصدم عليها. و بعد إجراء التجارب و الاختبارات أظهرت النتائج التحسن الواضح في الخصائص الميكانيكية مع تأثير محدود على متانة الصدم لنوعي الفولاذ الكربوني عند معالجته بالتيارات عالية التردد، كما أظهرت إمكانية التحكم بهذه الخصائص من خلال تغيير بارامترات طريقة التقسية.
The effects of induction hardening on mechanical properties of two kinds of carbon steel (0.59%C , 0.35%C) that are widely used in local industry, were discussed by exposed specimens that were induction hardened with different values of power and inductor's speed to hardness, tensile, and impact tests. The results of tests showed that the mechanical properties become greater with slight decrease in impact energy of carbon steel when induction hardening is used, and showed the possibility to do control on product's properties by make control on treatment parameters .

In this research, has been studied the spread of chromium atoms mechanism, and mechanical and chemical and properties of the diffusion chrome coating layer in low carbon steel, which is considered one of the surface treatment techniques. Where many p
ractical experiences were carried out in the powdery saturation milieu to form a diffusion coating layer containing atomic chromium who will spread inside the painted
surface, and has studied some mechanical and chemical properties after doing diffusion chrome coating.
The tests results showed that the tensile strength and micro hardness and chemical corrosion resistance improved after the diffusion chrome coating, also increased the depth of coating layer By increasing the retention time in the oven and temperature, where this relationship is reflected with curve of the second degree. Conversely ductility decreased.
Search results confirm the possibility of using diffusion chrome coating as a promising treatment in raising the efficiency of machinery elements that prone to oxidation or chemical corrosion in different temperatures.
Thepaper studies the mechanical properties ofsteel fibers reinforced lightweight
concrete.This kind of concrete is produced by usingscoria aggregateswhich can be found
abundantly in Syria. Thelightweight concrete mixeswere designed for three differ
ent
percentage of steel fibers (0, 0.5, 0.75)%.
Different tests were performed to determine mechanical properties of product
concrete such as compressive strength, elasticity modulus, splitting tensile strengthand
flexural strengthalso; the stress–strain diagram of produced lightweight concrete was
established under compression.
The results showedanincrease of the compressive, splitting tensile and flexural
strengths reach up 16.9%, 25.6%, and 53.6% respectivelywhen the steel fibers were used.
Also the results indicated the importance of using the steel fibers to improve the
performance of concrete and change its brittle behavior to ductile behavior.
This paper provides a mechanism to study aluminum diffusion microstructure, phase
structure and different properties of the aluminized layer in carbon steel.
The results of aluminized treatment in saturated medium lead to the formation of diffusion
layer coating that contains iron aluminide and a- solid solution of aluminum in the unit cell of
iron.
The effect of aluminizing process parameters on the aluminizing layer, especially the
effect of temperature and time, has been shown to increase the depth of the aluminized layer
when temperature and time increase, but the effect of temperature is greater than time.
Design of experiments (DOE)
had been used in the study, and the results had been evaluated by the
surface response method. The results showed that the welding
current is the main parameter by its effect on the mechanical studied
properties and the parameters values which give the best responses
had been determined.
In this work, Ck85 carbon steel was subjected to cyclic heat
treatment.
Process that consisted of cyclic short-duration (3.4 minutes)
holding at 800 C (above Ac3 temperature) followed by forced air
cooling. After 8 cycles (about a total 1 hour du
ration of heating and cooling cyclic), the microstructure mostly contained fine ferrite
grains and spheroidzed cementite. This microstructure possessed
an excellent combination of strength and ductility. The disintegration of lamellar pearlite through dissolution of cementite
at boundaries lamellar during short-duration holding above Ac3
temperature, and the generation of lamellar defects during nonequilibrium forced air cooling were the main reasons of
accelerated spheroidization. The strength initially increased mainly
due to the presence of finer microconstituents (ferrite and pearlite)
and then marginally decreased with the elimination of lamellar
pearlite and appearance of spheroid cementite in the microstructure.
