TITLE INFLUENCE OF DENSITY ON WEAR BEHAVIOR OF

SINTER-FORGED Fe-C-Mo LOW ALLOY STEELS

EFFECTS OF TITANIUM (Ti) & TUNGSTEN (W)

ADDITION ON WEAR BEHAVIOUR OF POWDER

METALLURGY (P/M)PLAIN CARBON STEEL (Fe-1%C)

OBJECTIVE In this project aim to study the influence of density on wears behavior of sinter- forged low

alloy steels. Elemental powders of atomized iron

(Fe), graphite(C), molybdenum (Mo) were

weighed and mixed in a pot mill to yield the

composition of Fe-0.5%C and Fe-0.5%C-2%Mo,

then compacted as circular disc with suitable

die-punch 100T capacity hydraulic press and

sintered at temperature of 1100oC 10oC to

obtain discs of diameter 50mm and 7mm

thickness. Then the sintered specimen was kept

in between two flat plate dies and subjected to

cold upsetting in Compressive Testing Machine

(CTM). The specimens were subjected to two

different loads in order to get two different

densities for each alloy, namely 83% and 87% of

theoretical density. The sintered and densified

performs of various densities of alloy steels are

subsequently machined to get the required test

specimens. Using design of expert (DOE)

software, the sliding wear experiments were

planned on pin-on-disc Tribometer.

The present work aims to study the effects of

Titanium (Ti) and tungsten (W) addition on wear

behavior of Powder Metallurgy (P/M) plain

carbon steel. Elemental powders of atomized

iron (Fe), graphite (C), and titanium and

tungsten were weighed accurately and

homogeneously mixed to compose an alloy

powders of Fe-1%C, Fe-1%C-1%Ti, Fe-1%C-1%W,

Fe-1%C-1%Ti-1%W, then compacted into

cylindrical billets of size (Ø25X33mm) using

suitable circular die-punch set in a 100T capacity hydraulic press. The compacted specimens were

subjected to sintering and subsequently sintered

specimens were once again heated to a

temperature 1000 C and hot upsetting was

carried out on the heated specimens. Then the

machining was performed on hot upset

specimens to get wear test specimens of size

φ6X50mm. Using design of expert (DOE)

software, the sliding wear experiments were

planned on pin-on-disc Tribometer.

CONCLUSION

The results are represented on a 3D Surface

graph for comparing the response of various

densities of both the alloy steels. It is observed that the increasing density of alloy steels

adversely affects the wear resistance of the alloy steels and mass loss is increased. It was found

that the addition of Mo significantly improves the wear resistance of the alloy steels irrespective of the densities due to hard phase carbides present

in the microstructure. Mo addition contributes to

increase in hardness of alloy steels. It is observed from the optical images of wear pattern, that

the plain carbon steel is found to be subjected to uniform wear, as the evenly spread wear track

The results are represented on 3D &2D Surface

plot for comparing the response factors of both

the alloy steels The plain carbon steel (Fe-1%C)

exhibits higher mass loss and lower frictional

coefficient. Addition of 1%Ti and 1%W to the

plain carbon steel significantly enhances the

wear resistance and hardness of the alloy steel

due to the formation of carbides of W and Ti

alloying element. It is found that the

delamination wear is predominant at higher

loads on both the alloy steels. The generalized

mathematical correlations are generated to mass

loss and coefficient of friction for the alloy steels and also validated with the experimental results.

appeared in the images. On the other hand the

Mo alloyed steel is subjected to non-uniform

wear due to the presence of hard-phases in the

microstructure. Delamination is found to be a

common mode of wear for carbon and alloy

steels. Coefficient of friction is found to be

reduced when mass loss is high due to more

material removal and fresh surface contact.

Uniform wear is observed in the plain carbon

steel and non-uniform wear pattern is observed

for Ti and W alloyed steels.
